Arched girder connecting structure with arch rib located in middle of bridge floor and construction method of arched girder connecting structure
The invention discloses an arched girder connecting structure with an arch rib located in the middle of a bridge floor and a construction method thereof.The arched girder connecting structure comprises a box type arch column upper top plate and a lower bottom plate, the box type arch column penetrates through the upper top plate and the lower bottom plate, two webs and a transverse partition plate are arranged on the lower bottom plate, a stiffening rib plate group is arranged between the two webs, and the stiffening rib plate group is arranged between the two webs. The web plates and the box type arch columns are connected into a whole, an extension plate is arranged at the bottom of the upper top plate, a connecting plate is arranged between the upper top plate and the lower top plate, the connecting plate is connected with a transverse partition plate, and an arch hole is formed in the connecting plate; according to the arched girder connecting structure with the arch rib located in the middle of the bridge floor and the construction method of the arched girder connecting structure, the problem of stress concentration of welding seams is greatly solved, it is guaranteed that enough welding space and maintenance space exist in all parts of components, construction efficiency is greatly improved, the problem of stress concentration of main girders at supports is solved, and the problems that in the prior art, stress concentration of the welding seams is large; the welding joint fatigue strength is low, the construction efficiency is low, the partition plate stress is large, and the stability coefficient is low.
本发明公开了一种拱肋位于桥面中间的拱梁连接结构及其施工方法，包括箱型拱柱上顶板，所述箱型拱柱穿过上顶板，以及下底板，所述下底板上设置有两个腹板和横隔板，两个所述腹板之间设置有加劲肋板族，所述腹板与箱型拱柱连接成整体，所述上顶板底部设置有延伸板，所述上顶板与下顶板之间设置连接板，所述连接板连接横隔板，所述连接板上设置有拱洞；该拱肋位于桥面中间的拱梁连接结构及其施工方法，极大降低了焊缝的应力集中问题，确保在构件各处都有足够的焊接空间和养护空间，大幅提高施工效率，降低了支座处主梁应力集中问题，解决了现有技术焊缝的应力集中较大，焊缝疲劳强度低，施工效率低及隔板应力大，稳定系数低的问题。
